The improved lure carriage is provided with avery simple electrically operated mechanism for'movin the lure 1 from an operat ve to an inoperative position 1 s so arrai'rgedas to permit imitation of jumping moveinentover hurdles and the like; There isalso provided animpr'o'ved overhead Pa l track system for operating the carr age thereon which, witha minimum ofmaterial se cures su port of utmost rigldity ands hfiness fertile railsupon which the lure carriage is run; ."R-efeifring to the drawing, an oval racingtrack 1 as shown inFig; 8has disposed along OF CHICAGQ', ILLINOIS, ASSIGNOR TO HARRY B.

the inner side thereof a series of posts 2, the posts being formed of T-shape angle iron secured to suitable foundation blocks 8, of concrete for instance, and stiffened by braces 4 against the foundation blocks. The upper end of each post is bent outwardly towards the track 1 and forms an arch 6. Extending between the posts within the inner space of the arches 6 are two girders 7 and 8 formed of angle iron, one girder 7 being suitably se- -cured to the upper ends of the upstanding posts 2 and the other girder being secured to the bent-over portion 9 of the posts.

-' The angle irons 7 and 8 thusdefine an oval runway along the track and on the horizontal portions of said angle irons there are sup ported, two railsll and 12, the rails'being' suitably secured to the angle irons as by means of bolts or welding; Ajrail track is thus obtained comprisii'ig two spaced rails supported on an overhead structure with a free space between the rails.

A carriage is arranged to run 011 this rail track, the truck of the carriage consisting merely of two driving motors 16 and 17and a pair of straps 18, 19, to which the two motors are secured. The motors are of the ordi nary commercial form having each a familiar frame with four legs20 at the base thereof. These legs are suitably connected, as by means of bolts 21, to the straps 18 and 19. The straps are'm'a de of an elastic material such as tempered steel in order to permit play between the motor in the front portionand the motor in the rear portion and adjustment of the individual Wheels to the track while tending to maintain all four wheels on the track and avoiding slippage of one or the other wheel. The motor frames with the straps 18, 19, running therebetween thus constitute a very simple truck frame Without requiring any complicated structures, full use being made of the fram'eof the motors.

Each of the motors 16, 17 has directly mounted on the shaft stubs 24 extending on both sides thereof flanged Wheels 25 adapted toengage the rails 11 and 12 to run thereon and be guided thereby along the track. The shafts 24; with the associated wheels 25 are mounted on ball bearings 26 as illustrated in Fig. 5, the inner race 27 of the ball bearings being held on a sleeve member 28 which is secured to the frame of the motor in place of the ordinary sleeve bearing, the outer race 29 of the bearing being secured to the hub of the wheel 25. a Spring washers 30 between the end of the sleeve 28 and the adjacent portion of the Wheel 25 serve to establish a good conf ducting connection to the wheels so as to proerating speed with relatively small motorss Thus, aspeed of fifty to sixty miles per hour may be obtained with the motorshaving each a rating of only three-quarters of a horsepower. 1 In order to hold the carriage on the t track and prevent jumping on account of its;

light weight'and high'operating speed, the carriage is provided with a'plurality of guide rollers 31 supported on suitable brackets 32 extending from underneath the side straps 18 and 19, the rollers underlying the rails and 12 and the angle irons 7 and 8 so as to oppose.

upward movement of the carriage in a direction away fromthe track. Either one or two p'airs of rollers may be provided, but in the preferred construction twofpairs of rollers are used disposed underneath the two pairs of wheels of the front motor 16 andthe rearvmotor 17 In addition to the electric supply current connection through the grounded rails 11, 12

and the wheels 25 of the carriage'there are provided two additional supply connections in the form of a pair of'collector forks 35, 36,

, that are insulatinglysupported side by side on an arched bracket 37 that is mounted on the two sidestraps 18, 19 by means of bolts 38. Thecollector members 35 and 36 are arranged to cooperate with two trolley conductors'll, 42 that are insulatingly mounted on "suitable insulators 4c3 that are secured to theupper portion of the arches 6, the conductors running along the track soas to supply current to the'collector members 35 and 36.. Suspended from the lurecarriage is a lure mechanism includingla lure arm 51carrying at its end a lure '52, The construction of the lure mechanism is; described and claimed in the 'co-pending application, Serial; No.

7 On the curved portions of the track the outer rail 12 is supported at ahigher level 1 than the inner rail 11 toform a banked rail track, as shown in Fig. I, in order to reduce ing reflectors 110, there being provided conduits 111. running along the postsland extending beyond the upper portions thereof,

the endsof the conduits vwith the reflectors 110 being supported on suitable braces 112 that areanchored on thearchesl f l Duet'o'the employment of direct motordrive bymounting the four wheels of the carriage directly on the shafts of the two driving motors it is possible to obtain a high driving speed and quick acceleration, such as is, required indog' racing apparatus with an eX- ceedingly small total weight of the carriage. In thisway the cost of the equipment for dog racing tracks and of the operation and maintenance of the same is cut down to a fraction of the cost of prior art apparatus. Inthe improved apparatus of myinvention the entire weight of the carriage isutilized to ob- 'tain the attractive effort since boththefront wheels, as wellas the rear wheels of the car-v riage, are motor driv'enL The employment of a small light weight -'driving carriage makes it, alsopossible to avoid'the expensive railstructures used in the prior; art dog racing. grounds. 'With the improved 1 carriage, a relatively simple and inexpensive runway on which the carriage is guided, is all'that is necessary for properly operating the .race. track. The utilization of small motors also reducesto a minimum the current consumpv tion'required'to drive and operate the carriage. The entire structure is light and may be readily dismantledand installed, the small weightoftheycarriage permitting'it' to be transported readily from place'to place.

' Many modifications of the inventionwill suggest themselves to those skilled in the art 'and it is, accordingly,..desired that theappended claims be'given a broad construction commensurate with the scope of the invention..
